Applied NDE and
Geophysical Assessments
Olson Engineering can test and provide insight on a variety of different man-made structures using NDE methodologies. Our geophysics department can determine the subsurface conditions at any site. Our techniques can be applied to many locations and situations.
Nondestructive Testing & Evaluation
Common Applications
Concrete repair, quality assessment, and service life assessment
Assessment of concrete quality, strength, and subsurface defects (voids, cracks, delaminations, honeycombing, cold joints, etc.)
Evaluating the structural integrity of buildings, bridges, and other structures
Investigating the integrity of pavements, slabs-on-grade, and the supporting subgrade materials
Characterizing reinforcement, conduits, and other subsurface features
Assessing the depth, condition, and integrity of foundations
Investigating the integrity and location of pipes, conduits, tunnels and mineshafts
